What makes champagne fizz?

Nooo, it ain't Carbon Dioxide, it's dirt!
   Carbon dioxide particles would evaporate invisibly in a perfectly smooth and clean glass, so for a long time scientists had accepted that it was slight imperfections in production of the glass that made the bubbles form.
   Howbeit, advancement in photographic techniques have now displayed that these demerits in design were much too small for the bubbles to latch onto. What causes these bubbles are the microscopic particles of dust and fragments of fluff that enable them to form in the glass.
   Practically speaking, the 'dirt' in the glass act as condensational nuclei for the dissolved CO2

  According to Moët et Chandon, there are about 250million bubbles in a bottle of champagne. It was believed to be first invented by Dom Perignon, a Benedictine monk at the Abbey of Hautvillers in the 17th century, purely by mistake! Unlike wine, that is made up of one type of grapes, champagne is made from three types of grapes; one variety of white grapes, the Chardonnay and two varieties of black grapes, Pinot Noir and Pinot Meunier.

   What's interesting is that, despite of its white colour, champagne is mostly made up of black grapes! The black grapes are pressed just enough to extract no more than the juice and the skin chucked into caskets in the wine cellar, to undergo fermentation.
   The pressure in a champagne bottle is three times that of a car tire, measuring at ninety pounds per square inch.
   The velocity at which the cork leaves the bottle has been recorded to be between 38-40 mph (61-64kmph). It can pop out at up to 100 miles per hour. The furthest flight-distance of a champagne cork was a recorded 177 feet, 9 inches, done by American Heinrich Medicus in 1988.
   Marilyn Monroe is believed to have taken a 'champagne bath', using about 350 champagne bottles to fill the bathtub.
   The world's tallest champagne bottle is about seven feet upright and has the capacity to fit up to 22 normal-sized bottles of champagne. It was unveiled at a festival in Italy.
   There is a rumour that a few bottles of Heidsieck & Co. Monopole Blue Top Champagne Brut was recently recovered from the wreckage of the Titanic and still tasted great!
